Frigidaire Refrigerator Control Board Replacement Guide — Cost, Signs & DIY Tips
Frigidaire refrigerator control boards vary significantly by model tier. Standard models (FFTR/FFSS) use a relatively simple board that manages the compressor, defrost timer, and fans. Gallery models (FGHB/FGSS) with EvenTemp twin evaporators have substantially more complex boards that independently control separate cooling zones for the fresh food and freezer compartments. Professional models (FPBS/FPRU) use similar architecture to Gallery.
Board Location by Model
| Model Tier | Board Location | Access Method |
|---|---|---|
| Standard top-freezer (FFTR) | Upper rear wall inside fresh food compartment | Remove the plastic cover plate (1–2 screws) |
| Standard side-by-side (FFSS) | Behind the temperature control panel at top of fresh food section | Remove control panel cover |
| Gallery French door (FGHB) | Behind the external display/controls on the door front | Remove display bezel (plastic clips + screws) |
| Gallery side-by-side (FGSS) | Upper rear inside or behind display | Model-dependent |
| Professional (FPBS/FPRU) | Behind display panel | Similar to Gallery |

Symptoms of Board Failure
- Both compartments too warm despite compressor running — on EvenTemp models, the board controls dampers that direct cold air between compartments. A failed board may not open the damper to the fresh food section
- Display shows error code — SY CE (communication error between boards on multi-board models), SY EF (evaporator fan circuit), or number codes varying by model year. Check the service sheet (behind toe plate or inside a compartment panel) for your model's specific code table
- Temperature fluctuates widely — the board's thermistor input circuit has drifted, causing it to misread temperature and cycle the compressor erratically
- Compressor does not start despite good start relay and windings — the board's compressor relay output is not energizing. The board controls when the compressor runs; if the output circuit fails, nothing happens
- Ice maker not working despite water supply being connected — the board controls the ice maker fill valve timing. A board fault can prevent the fill cycle from initiating
- Defrost cycle not running — evaporator ices over — the board manages defrost timing (every 6–12 hours). If the defrost output fails, ice builds up on the evaporator, blocking airflow
Board Cost

| OEM main board (Standard models) | $60–$150 |
| OEM main board (Gallery/Professional) | $100–$250 |
| Electrolux cross-reference | 10–20% less sometimes |
| Display interface board (if separate) | $50–$120 |
| Professional labor | $100–$200 |
| DIY total | $60–$250 |
| Professional total | $160–$500 |

Replacement Procedure (Standard — Upper Rear)
- Unplug the refrigerator.
- Remove food from the upper shelves to access the rear wall cover.
- Remove the cover plate (1–2 Phillips screws). The board is mounted behind it.
- Photograph all wire connectors. Disconnect each one (they are keyed but noting positions prevents mistakes).
- Remove the board mounting screws (2–4 Phillips).
- Install the new board. Reconnect all wire harnesses per your photos.
- Replace the cover plate. Plug in the refrigerator.
- Allow 24 hours for the unit to stabilize at the target temperature before evaluating whether the repair is successful.
Replacement Procedure (Gallery — Behind Display)
- Unplug the refrigerator.
- Remove the display bezel — gently pry off plastic clips around the edges. Some models have hidden screws under trim pieces.
- Disconnect the ribbon cable or wire harness connecting the display to the main board.
- The main board is behind the display. Remove mounting screws. Swap boards.
- Reconnect display, replace bezel. Plug in.
- Set temperature to the recommended settings (37°F fresh food, 0°F freezer). Wait 24 hours.
Tools: Phillips #2, flat-head screwdriver (for prying bezel clips). Time: 20–40 minutes.

EvenTemp Twin Evaporator Implications
Gallery models with EvenTemp have independent cooling for the fresh food and freezer compartments. The control board manages two evaporator fans, two thermistors, and a motorized damper between the two zones. If only one compartment is not cooling, the issue may be a failed damper motor, a single thermistor, or a board output controlling that specific zone — not necessarily the entire board. Diagnose which zone is affected before ordering a board.
Defrost System Diagnosis
If the evaporator is iced over (you see frost on the freezer rear wall panel), the defrost system has failed. Three components to test before blaming the board: defrost heater (continuity test), defrost thermostat (continuity at room temp — should be open; at freezer temp — should be closed), and the board's defrost timer output. If the heater and thermostat test good, the board is not initiating the defrost cycle.

FAQ
Where is the control board on my Frigidaire refrigerator?
Standard models: behind a cover plate at the upper rear of the fresh food compartment. Gallery/Professional: behind the display panel on the door or front of the unit.
Can a bad control board cause ice buildup in my Frigidaire freezer?
Yes. The board controls the defrost cycle. If the defrost output fails, the evaporator ices over, blocking airflow and causing the freezer to warm while the fresh food section stays cold.
What does SY CE mean on my Frigidaire refrigerator?
Communication Error — the display board cannot communicate with the main board. Check the ribbon cable connection first. If connected, one of the two boards has failed.
How long should I wait after replacing the board to check temperatures?
24 hours. The refrigerator needs time to pull down to target temperatures after being warm during the repair.
